No external bypass capacitor is needed for achieving the low noise level of 30 µVrms. In addition to the noise levels, MAS9162 excels in dropout voltage (95 mV typical at 50 mA) and in start-up time (typically 10 µs from start-up to within ±1% of VOUT(NOM)). The Equivalent Series Resistance (ESR) range of output capacitors that can be used with MAS9162 is very wide. This ESR range from a few mΩ up to a couple of Ohms combined with no minimum output current requirement makes the usage of MAS9162 easier and low in cost. Also the minimum output capacitance requirement is very low. This combined with very short start-up time makes it possible to switch the regulator off and on even in timing critical and/or noise sensitive applications. An internal thermal protection circuit prevents the device from overheating. Also the maximum output current is internally limited. In order to save power the device goes into sleep mode when the regulator is disabled. )($785(6 • No External Bypass Capacitor Needed • Optimized for Fast Start-up • Internal Thermal Shutdown • Short Circuit Protection • SOT23-5 Package • Pin Compatible with MC33761 • Several Output Voltage Options Available, See Ordering Information p. 8 $33/,&$7,21 • RF-Oscillators • Cellular Phones • Cordless Phones • Pagers • Battery Powered Systems • Portable Systems • Radio Control Systems 3,1 &21),*85$7,21 VOUT 5 4 62AX 1 2 3 NC For Top Marking Information see Ordering Information p. 8 Top View VIN GND CTRL 1 (8) DA9162.001 25 October, 2001 3,1 '(6&5,37,21 3LQ 1DPH VIN GND CTRL N/C VOUT 3LQ 1 2 3 4 5 7\SH P G I O )XQFWLRQ Power Supply Voltage Ground Enable/Disable Pin for Regulator Not Connected Output G = Ground, I = Input, O = Output, P = Power %/2&.
